A big problem with the current i8042 debugging option is that it outputs

years, nobody has started using it in an upstream kernel, and the platforms
that were interested in it have moved on to devicetree, which can be used
to configure the sequence without requiring kernel changes. The method is
also incompatible with the way that most architectures build support for
multiple platforms into a single kernel.
Now the code is producing warnings when built with gcc-5.1:

Input: adxl34x - add OF match support
The I2C subsystem can match devices without explicit OF support based on
the part of their compatible property after the comma. However, this
mechanism uses the first compatible value only. For adxl34x OF device
nodes the compatible property will contain the more specific
"adi,adxl345" or "adi,adxl346" value first. This prevents the device

Fix this by adding an OF match table with an "adi,adxl345" compatible

backward-compatible with the ADXL345 with differences handled by runtime

Input: alps - use more accurate coordinates for first touch in semi-mt mode
All alps semi-mt touchpads give us the following data when 2 (or more)
fingers are touching: 1 more or less accurate touch for the first finger
down, and a bitmap with columns and rows in which 1 or more fingers are
seen resulting in a crude (low res) bounding box.
So far for v3, rushmore and v4 touchpads we've been reporting the
coordinates of 2 opposite corners of the box when 2 fingers are touching.
Ignoring the much better resolution data given in the normal position
packet.
This commit actually uses this data for the first touch, figures out which
corner of the bounding box is closest to the first touch, and reports the
coordinates of the opposite corner for the second touch, resulting in
much better data for the first touch and for the single touch
pointer-emulation events.
This approach is similar to the one in alps_process_bitmap_dolphin, that
function takes the single accurate touch info, calculates the distance to
the center of the bounding box, and then puts the 2nd touch mirrored to
the center. The downside of that approach is that if both touches move
slowly in the same direction, the bounding box will stay the same for a
while (as it is low res) and the second touch will thus been seen moving
in the opposite direction until the bounding box actually changes, and
then the second touch snaps to its new position resulting in a saw tooth
pattern in the coordinates for the second touch, hence this new approach.
This commit fixes 2 finger scrolling being choppy / jumpy on these
touchpads.

Input: smtpe-ts - wait 50mS until polling for pen-up
Wait a little bit longer, 50mS instead of 20mS, until the driver starts
polling for pen-up. The problematic behavior before this patch is applied
is as follows. The behavior was observed on the STMPE610QTR controller.
Upon a physical pen-down event, the touchscreen reports one set of x-y-p
coordinates and a pen-down event. After that, the pen-up polling is
triggered and since the controller is not ready yet, the polling mistakenly
detects a pen-up event while the physical state is still such that the pen
is down on the touch surface.
The pen-up handling flushes the controller FIFO, so after that, all the
samples in the controller are discarded. The controller becomes ready
shortly after this bogus pen-up handling and does generate again a pen-down
interrupt. This time, the controller contains x-y-p samples which all read
as zero. Since pressure value is zero, this set of samples is effectively
ignored by userland.
In the end, the driver just bounces between pen-down and bogus pen-up
handling, generating no useful results. Fix this by giving the controller a
bit more time before polling it for pen-up.

Google Pixel 2 (2015).
While newer version of ACPI standard allow use of device-tree-like
properties in device descriptions, the version of ACPI implemented in
Google BIOS does not support them, and we have to resort to DMI data to
specify exact characteristics of the devices (touchpad vs. touchscreen,
GPIO to button mapping, etc).
Pixel 1 continues to use i2c devices and platform data created by
chromeos-laptop driver, since ACPI does not enumerate them.

Input: add vmmouse driver
VMMouse enables low-latency mouse-cursor-movements for VMWare and QEMU
guests. By removing the guest cursor and using the host as a guest cursor
the cursor movement appears instant although in reality there is some lag.
To be able to do this, the host's view of the cursor position must exactly
match the guest's view and an absolute pointer device is needed. Enter the
VMMouse. While the VMMouse driver has historically been an Xorg user-space
driver, implementing it as a kernel imput driver enables rootless Xorg and
new compositing display servers for VMware guests.

To save people some time let's document that we do not want new quirks for
"force-release" keys in the kernel and that they should patch userspace
(udev) instead.
